frequency excursion

基本解释

The OFDM is sensitive to the synchronization of the OFDM symbol and the carriers' frequency excursion.
OFDM系统存在对数据符号同步和载波频率偏移极为敏感的问题。
Considering the uncertainty of frequency excursion, the scheme of signal capturing of correlate searching, FFT capturing is bring forward.
考虑到短波信道频率偏移的不确定性提出了相关搜索、FFT捕获的信号捕获方案。
Finally, an example of simulation system is presented, and the influence of frequency excursion on performance of multi-tone continuous wave jamming is analyzed and simulated.
最后，给出了仿真系统实例，分析并仿真了频率偏移对多频连续波干扰性能的影响。
